Abstract

L'invention concerne des circuits et des procédés destiné à être utilisés dans un émetteur avec ou sans fil pour compléter la production numérique de signaux à modulation d'enveloppe non constante. Dans ces circuits, un processeur de signaux numériques permet de décomposer un signal prédéterminé ayant une propriété indésirable en un ou plusieurs fragments de signal n'ayant pas ladite propriété indésirable. Dans un mode de réalisation préféré, le signal prédéterminé est préalablement traité par application d'un processus de décomposition préalable à un autre signal à partir duquel le signal prédéterminé est obtenu, l'autre signal étant ainsi décomposé en un ou plusieurs fragments de signal préalablement traité ayant une propriété améliorée par rapport à l'autre signal. Pour les schémas de modulation OFDM, cette propriété indésirable peut avoir un rapport puissance moyenne sur puissance crête relativement élevé. Les signaux formée à partir des fragments de signal sont convertis en signaux analogiques et traités par des circuits analogiques puissants limités en une gamme dynamique, c'est-à-dire des amplificateurs de puissance de classe S (et, pour les applications sans fil, des convertisseurs élévateurs à point de compression bas), avant d'être recombinés pour être émis.
